, use the same.

This invention relates to envelops, and one of the principal objects of the same is to provide an envelop made from a single piece of paper without waste and said envelop being designed to be folded to form the envelop and to be. sealed at the time the envelop 1s to be used for mailing.

Another object of the invention is to provide an envelop which can be made from a single piece of paper without waste and said envelop forming a substantially flat blank to be folded and sealed at one operation, so that when the letter or contents of the envelop is ready to be mailed, the envelop may be folded and sealed at one operation. V

Still another object of the invention is to provide a flat blank envelop having the edges and lower margin turned inward and provided with a coating of adhesive material, while the upper flap is adapted to be folded over to inclose the letter to be mailed and this flap is provided with a strip of adhesive material to be connected to the bottom margin for sealing the envelop, while the side edges are also adapted to be coated with adhesive to be together at the time the envelop is to bemailed.

The foregoing and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which,

Figure 1 is a plan view of the inner side of the blank for forming the envelop, Fig. 2 is a plan view of the blank in which the upper flap is turned inward in position to hold a letter or other missive in place prior to folding the envelop and securing the side edges and sealing the envelop. Fig. 3 is a perspective view of the envelop when the two side edges are united and the letter has been placed in the envelop and it is in condition to be sealed along the upper margin or edge, one layer of the envelop being broken away for a portion of its length, and Fig. 4 is a vertical sectional view through the envelop and contents after it has been sealed.

Referring to the drawing, the numeral 1 designates one half of the envelop and 2 is the other half adapted to be folded on the line 3 at the time the envelop is to be used for mailing, the side marginal edges 4: of the envelop are folded inward and an adhesive material 5 is applied thereto, the lower edge or margin 6 of the envelop blank is also folded in and as shown is folded under the corner 7 of the side margins 4. The holding flap 8 for the letter or missive is cut away on the opposite side as at 9, and when folded over onto the body portion 2 of the envelop as shown in Fig. 2, the corners of the side margins 4 are disposed underneath said flap. After the flap is folded, a strip of adhesive material 10 is applied thereto. When the letter or missive a is placed in the envelop, the flap Sis bent over to hold it in place, as shown clearly in Fig. 4E and the envelop is then ready for sealing, the adhesive material 5 at the sides of the envelop may be moistened and the strip 10 of adhesive material may be also moistened, and by folding the envelop on the line 3, the sealing is accomplished and the envelop may then be addressed upon either side, since both sides are plain and without overlapping portions.

As one of the objects of this invention, it should be stated that the sealing operation can be better performed by simple machinery, since it merely moistens the side strips and one end strip of the adhesive material and then is ready for folding to pass between rollers for uniting the two members of the envelop.

Slight changes in details may be resorted to without departing from the spirit and scope of the invention as defined in the claim.

What is claimed is The herein described envelop comprising side margins folded over agamst the body portion of the envelop and provided with an adhesive substance, a bottom marginal strip In testimony whereof I affix my signature folded underneath sald side margins, and a in presence of tWo Witnesses.
